What Can Wireshark Really Tell You About an Encrypted Signal Conversation?

Networking and Computing Tips and Tricks / By

Views: 944Signal has a well-earned reputation as a secure messaging application. Messages, voice calls, video calls, files, and other Signal-to-Signal communications are protected using end-to-end encryption. Signal states that message and call contents cannot be accessed by Signal or other third parties because the communications are always end-to-end encrypted. So that raises an interesting Wireshark

End-to-End Encryption: A Privacy Victory or a Networking Blind Spot?

The CellStream Blog / By

Views: 852TLS 1.3, QUIC, HTTP/3, encrypted DNS, and Encrypted Client Hello increasingly conceal application and transport information that network operators traditionally used for troubleshooting, security inspection, filtering, performance optimization, and policy enforcement. Here is a little reference chart: This produces two defensible but conflicting positions: For most of the Internet’s history, and certainly for my

The TLS 1.2 Protocol Ladder

Networking and Computing Tips and Tricks / By

Views: 2,465I provide this information for reference when examining TLS in Wireshark. The TLS 1.2 protocol ladder (also called the TLS handshake ladder) describes the step-by-step sequence of message exchanges between a client and server as they negotiate a secure, encrypted connection. Think of it as a “ladder” where each side alternates rungs (messages) upward

Views: 2,989Let’s just start right out and say: contrary to the scare tactics made by some, that MPLS traffic has been exposed by the providers that operate MPLS, there has never been any validated evidence that such a breach has indeed ever occurred, other than some alleged errors in configuration. MPLS operates between L2 and
